Operating Instructions
Wiring Checkout
Operational Checkout
Before applying power to the SMARTLINK™ Control
Interface and SMARTLINK™ Valve Actuator Assembly,
perform the following wiring checkout:
Apply power to the SMARTLINK™ Control Interface and
SMARTLINK™ Valve Actuator Assembly and perform the
following operational checkout:
1)
2)
3)
4)
5)
6)
Verify that 120 VAC is not connected directly to
SMARTLINK™ Control Interface and Valve Actuator
Assembly. Both devices are powered by a 24VDC
supply. All output interface relay wiring from the
Control Interface is connected to 24VDC relay coils.
Verify the proper wire type and maximum wire length
requirements are satisfied for all connections.
Verify color code connections are correct on the 24V/
Data Connector of both the Control Interface and
Valve Actuator Assembly.
Measure the resistance between earth ground at the
user's panel enclosing the Control Interface and each
of the four signals wired to the Valve Actuator: F24
(Field +24VDC), FCOM (Field Common), DA (Data-A),
and DB (Data-B). The resistance should indicate an
open circuit (i.e., a resistance value greater than 10 6
Ohms). If an open circuit is not measured, damage or
incorrect wiring of the control network cable exists and
must be corrected.
Verify proper termination of shields for the 4-20mA
cables and the control cable between the Control
Interface and Valve Actuator Assembly.
If Maxon SMARTLINK™ Interface Relays are not
provided with the Control Interface, verify that all
required relays have a coil rating less than 30VDC
and 100mA. The output interface relay coils are
connected to the Control Interface, RO1 through RO5
terminals of the Relay Output driver connector.
Refer to SMARTLINK™ Reference Tables 1 through 5
(pages 7300-S-18 to 21) for all termination definitions and
wiring/shielding requirements.
Maintain the integrity of the Maxon enclosure by using
NEMA 4X or IP66 rated dust- and water-tight electrical
connectors. Use cable-sealing grips and strain-relief
loops for any cord or cable. Use internal sealing materials
on all conduit connections. Moisture can have a harmful
effect on device internals if permitted to enter through
wiring connectors. Ensure that the device connection is not
at a low point of the conduit to avoid condensation run-off
into the housing; install a drip loop if necessary. Make sure
that the access cover plate is in place and securely
fastened. All cover screws should be tightened using an
alternate cross-corner tightening pattern. Cover screws
should be checked periodically to ensure adequate
sealing protection.
1)
Verify the Control Interface Alarm light is off and the
Run light is on after powering up the system. If the
alarm light is on, see page 7300-S-15 to determine the
cause of the alarm and corrective actions.
2)
Place the user’s process controller into manual mode
or temporarily replace the 4-20mA position command
with a simulated 4-20mA current loop. With the
Control Interface command switch in the “Run”
position, move the position command signal slowly
from 4mA to 20mA and verify valve movement. The
position of the valve can be visually observed by the
“OPEN” or “CLOSED” markings on the machined
coupling that connects the actuator to the valve shaft. If
the application requires the 4-20mA position feedback
signal, measure this feedback current loop while
changing the position command and verify that the two
currents (input vs. output) are approximately equal
after pausing at several intermediate positions.
3)
If the process controller cannot be placed in manual
mode or if a simulated command signal cannot be
produced, the SMARTLINK™ assembly can be
placed in a local manual mode. (Refer to Command
A-0 and the general command entry instructions on
page 7300-S-11). Once the system is in manual mode,
drive the valve to its full open and closed positions
using the INC/DEC switch on the Control Interface.
4)
If installed, verify operation of each output interface
relay by measuring the presence and disappearance
of voltage on the relay’s contact. If a DIN Rail
Assembly is supplied with the Control Interface, the
terminals for each relay contact are shown in Reference Table 6 on page 7300-S-22. The Control
Interface relay driver output terminals are also
provided in Reference Table 6 to assist in testing of
interface relays when not supplied and pre-wired by
Maxon.
Do not remove power from an air valve actuator when
both 1) the valve is open more than 30 degrees, and 2) the
blower is running. Prior to power loss, ensure that the valve
position is less than 30 degrees open, and/or that the
blower has stopped. Failure to observe these precautions
can result in permanent damage to the valve actuator.

Review the factory default settings before changing any of the system configuration settings; in many
applications, modification of the default settings is not necessary. If a setting does need to be changed, follow the
procedure outlined below.
Procedure for Changing a System Configuration Setting:
a) Select and enter the required system configuration command.
b) After the command is entered, one of the numbered (0-9) lights will be on, indicating the current configuration
setting. (For example: If the lock configuration is set to #0, Lock Disable, the 0 light will be solidly lit after
Command C-5, Lock Enable/Disable, is entered successfully.)
c) Select the desired configuration setting by using the INC/DEC switch. As the INC/DEC switch is momentarily
pushed up or down, the selected setting changes as indicated by turning on the corresponding numbered
light (0-9).
d) Push the ENTER button after the desired configuration setting is selected. The numbered light that is lit to
indicate the selected configuration will momentarily turn off indicating the command is complete and the
configuration setting is saved.
e) To confirm the correct setting is saved, re-enter the command and verify the new setting by the numbered
light (0-9) indication.

Operating Instructions
Characterizing the valve
Valve characterization is necessary for changing
the relationship between valve position and the 420mA position command. This process permits field
adjustment of the “installed” valve characteristic
without mechanically adjusting the valve or external
linkages.
The SMARTLINK™ is pre-set to a linear slope, but
can be customized using either the 10 Point Characterization procedure (below) or the 19 Point Characterization procedure (page 7300-S-9).
10 Point Characterization
SMARTLINK™ is shipped with the configuration setting to easily adjust valve positions at 10 of the 19 position
indexes and automatically set the positions at the other 9 (intermediate) indexes.
SMARTLINK™ 10 Point Valve Characterization Procedure:
a) Place the process controller that commands SMARTLINK™ in manual mode and connect a 4-digit current
meter on the 4-20mA position output. Execute Command B-6 and verify the Auto Ramp function is set to
#1, Auto Ramp ON. If not set correctly, refer to page 7300-S-7 or Reference Table 7 on page 7300-S-23.
b) Execute Command A-2, Enter Position Setup Mode. In this mode, both the yellow and green run lights will
be flashing. The position command signal determines which of the 19 position indexes can be modified as
shown by the blinking numbered lights. Move the process controller’s output to either 0% (Index #0) or
100% (Index #9) to begin characterization.
c) With the ADJUST switch in the middle (ADJ) position, push the INC/DEC switch up or down to change the
valve position. Each push of the INC/DEC switch moves the valve 0.1 degrees. If the switch is held in the
up or down position for more than 3 seconds, the valve will move in 0.5-degree steps up to a total travel of 8
degrees from the stored valve position. (All the numbered lights will momentarily flash when this 8-degree
limit is reached.) After moving the valve to the desired position, press the ENTER button to save the
position setting. Record the valve position feedback in mA or %.
d) Move the controller’s output to the % or mA setting in the commissioning table (shown on page 7300-S-17)
for each consecutive whole digit index and repeat the adjustment procedure in Step c. With the auto ramp
function ON, adjustment at only the 10 whole digit indexes is necessary because positions at the intermediate indexes (0.5, 1.5, etc.) are automatically set to a value half way between the positions of the whole
number indexes (0, 1, 2, etc).
e) Execute Command C-6 to save the profile as a backup. Move the MODE switch to the RUN position and
put the user’s process controller in AUTO.

Operating Instructions
Characterizing the valve
19 Point Characterization
There are applications that require precision adjustment throughout the actuator’s control range. For these
applications, adjustment of all 19 positions is necessary using the procedure below.
SMARTLINK™ 19 Point Valve Characterization Procedure:
a) Place the process controller that commands SMARTLINK™ in manual mode and connect a 4-digit current
meter on the 4-20mA position output. Execute Command B-6 and set the auto ramp function to setting #0,
Auto Ramp OFF. (Refer to page 7300-S-7 or the Reference Table on page 7300-S-23 for changing configuration settings.)
b) Execute Command A-2, Enter Position Setup Mode. In this mode, both the yellow and green run lights will
be flashing. The position command signal determines which of the 19 position indexes can be modified as
shown by the blinking numbered lights. Move the process controller’s output to either 0% (Index #0) or
100% (Index #9) to begin characterization.
c) With the ADJUST switch in the middle (ADJ) position, push the INC/DEC switch up or down to change the
valve position. Each push of the INC/DEC switch moves the valve 0.1 degrees. If the switch is held in the
up or down position for more than 3 seconds, the valve will move in 0.5-degree steps up to a total travel of 8
degrees from the stored valve position. (All the numbered lights will momentarily flash when this 8-degree
limit is reached.) After moving the valve to the desired position, press the ENTER button to save the position setting. Record the valve position feedback in mA or %.
d) Move the controller’s output to the next % or mA setting in the commissioning table (shown on page 7300-S17) and repeat the adjustment procedure in Step c for all 19 position indexes. With the auto ramp function
OFF, the positions of adjacent indexes are not automatically ramped. Therefore, all 19 position indexes
should be visited during this procedure and adjusted if necessary.
e) Execute Command C-6 to save the profile as a backup. Move the MODE switch to the RUN position and
put the user’s process controller in AUTO.
If an unsafe operating condition is observed while characterizing the SMARTLINK™ in a parallel positioning
combustion application, follow the instructions below:
1. When SMARTLINK™ is in the Position Setup Mode for valve characterization, the ADJUST switch can be
pushed to the STANDBY position (down). This action will immediately move the valve to the Standby
position, overriding the 4-20mA position command.
2. The factory default Standby position is the valve position at Index #0, the minimum position in the profile.
While the ADJUST switch is in this position, no commands can be executed. The Standby position function
is inhibited when the MODE switch is in the RUN position (down).

2. If the a, b, or c command set light is not blinking, momentarily push the MODE switch in the CMD abc
position (up) or, change the position of the rotary CMD SEL switch. This will start the command set light
blinking and permit a command to be entered.
3. Select the desired command set by momentarily pushing the MODE switch upward to the CMD abc position.
Subsequent CMD abc switch entries will change the command set selection as indicated by the green
command set (a, b, c) lights.
4. Select the desired command number by changing the position of the rotary CMD SEL switch. When one of
the command set lights is blinking, the command number selected is indicated by the corresponding numbered (0-9) light being lit.
5. After the command set and number are selected, press the ENTER button. If all of the numbered lights flash
momentarily after the Enter button is pushed, a command entry error has occurred and the command was
not executed. If an entry error occurs, check if the unit is locked (i.e. alarm light blinking) or the ADJUST
switch is in the STANDBY position. If neither condition exists, check the specific entry requirements of the
command.

Operating Instructions
Locking the unit and entering passcodes
The SMARTLINK™ Control Interface is shipped with the lock function disabled and a factory default 4-digit
passcode or “combination” of 0,0,0,0. To lock the unit for the first time and change the default passcode, the
lock function must first be enabled (Command C-5) and the default passcode entered (Command A-7). After the
lock function is enabled and the unit is “unlocked”, a new passcode can be entered using Command C-4. If you
forget the passcode, call Maxon for the “master” passcode.
Procedure for Enabling the “Lock” Configuration Setting (Command C-5):
a) If the alarm light is blinking, the lock function is already enabled and the unit is in a “locked” state. Before
changing the passcode, the unit must be unlocked by entering the current passcode (Command A-7) using
the procedure below.
b) If the alarm light is not blinking, select and enter Command C-5, Lock Enable/Disable.
c) After the command is entered, one of the numbered (0-9) lights will be on, indicating the current configuration setting. If the #1 light is on, the lock function is already enabled and the procedure below can be
performed to change the passcode. If the #0 light is on, the lock function is disabled.
d) To select the #1 setting (Lock Enable), momentarily push the INC/DEC switch in the up position. The #1
light will now be on, indicating the new setting is selected.
e) Push the ENTER button. The #1 light will turn off indicating the command is complete and the configuration
setting is saved. The unit is now locked and the alarm light will be blinking. To change the current
passcode, perform the following two procedures (Command A-7 & C-4).
Procedure for Entering the Current “Lock” Passcode (Command A-7):
a) Select and enter Command A-7, Unlock Valve Configuration.
b) After the command is entered, the INC/DEC switch is used to select the first passcode digit. The digit
selected is indicated by a numbered light (0-9).
c) Once the first digit of the passcode is selected, push the ENTER button once. The numbered light should
momentarily turn off indicating the entry was accepted.
d) Repeat step b and c for the 2nd, 3rd, and 4th passcode digits. If the passcode was entered incorrectly, all the
numbered lights will momentarily flash after entry of the 4th and final passcode digit. If the passcode was
correct, the alarm light will stop flashing and will be turned off completely if no other alarms exist.
e) To change the current passcode, perform the procedure (Command C-4) on the following page.

Operating Instructions
Locking the unit and entering passcodes (continued)
Procedure for Entering a New “Lock” Passcode (Command C-4):
a) To enter a new lock passcode, the lock function must be enabled (Command C-5) and the current passcode
must be entered (i.e. the unit must be “unlocked” using Command A-7). See the 2 previous procedures if
these two command entry requirements have not been satisfied.
b) Select and enter Command C-4, Enter New Lock Combination.
c) After the command is entered, the INC/DEC switch is used to select the first new passcode digit. The digit
selected is indicated by a numbered light (0-9).
d) Once the first new digit of the passcode is selected, push the ENTER button once. The numbered light
should momentarily turn off indicating the entry was accepted. Write down the new digit for later use.
e) Repeat steps c and d for the 2nd, 3rd, and 4th passcode digits, remembering to write down each passcode digit
as they are entered.
f) Verify the new passcode by re-locking the unit (MODE switch to the RUN position and then back to the
middle, Command Entry position), and entering the new passcode using Command A-7 as described in the
procedure on the previous page.
Manual override of the 4-20mA position command input signal
Command A-0, Enter Manual Positioning Mode, is used to override the 4-20mA position command input.(This
command should not be used when the valve is in an operating process that requires continuous positioning based
on the 4-20mA input signal.)
Procedure for Entering Manual Positioning Mode (Command A-0):
a) To enter the Manual Positioning Mode, the position command input signal must be first driven to 4ma or less.
b) Select and enter Command A-0, Enter Manual Positioning Mode. If the numbered lights flash momentarily
after entering Command A-0: 1.) the position command may not be less than 4mA, 2.) the adjustment mode
switch may be in the STANDBY position, or 3.) unit may be “locked” to prevent tampering.
c) After entering the command, the yellow manual (MAN) light will be on and RO5 (Relay Output driver #5) will
energize the Manual Control relay (if installed). The INC/DEC switch can be used to move the valve open or
closed. If the adjustment mode switch is in the INDEX position, the INC/DEC switch is used to move between
the 19 position “indexes”. If the adjustment mode switch is in the ADJ position, pushing the INC/DEC switch
up or down changes the valve position in 1.0 degree steps. If the INC/DEC switch is held in the up or down
position, the position is continuously adjusted until the maximum or minimum position is reached. When the
max or min position setpoint is reached, all the numbered lights will momentarily flash.
This command should not be executed when the valve is part of an operating process that requires continuous, closed-loop valve positioning.
d) To return control back to the 4-20mA position command input, move the MODE switch to the RUN position
(down).

Operating Instructions
High and low valve position limits
The high and low limits are automatically set when the user adjusts the maximum (Index #19) and minimum
(Index #0) valve position settings. If different high and low limits are required (other than the default or automatically set limits), Command B-4 and Command B-5 can be executed using the procedure below.
Command B-4 is a configuration command that is used to adjust the high limit position threshold. Relay driver
Output #3, RO3 will energize the optional High Position Limit relay when the valve position is equal to or greater
than the stored high limit position threshold. The high limit threshold has a factory default of 80.0 degrees and is
automatically set to 1.0 degree less than the maximum valve position when modified using Command A-2, Enter
Position Setup Mode, or A-5, Set Max Position & Min/Max Ramp. If the factory default or automatic 1.0
degree offset is acceptable, execution of Command B-4 is not necessary.
Command B-5 is a configuration command that is used to adjust the low limit position threshold. Relay driver
Output #4, RO4 will energize the optional Low Position Limit relay when the valve position is less than or equal to
the stored low limit position threshold. The low limit threshold has a factory default of 0.0 degrees and is automatically set to 1.0 degree above the minimum valve position when modified using Command A-2, Enter Position
Setup Mode, or A-6, Set Min Position & Min/Max Ramp. If the factory default or automatic 1.0 degree offset
is acceptable, execution of Command B-5 is not necessary.
Procedure for Manually Adjusting the High or Low Limit Position Threshold (Command B-4 or B-5):
a) Before entering Command B-4 (or B-5), the unit must be in the Manual Positioning Mode. (Execute Command A-0, as described on page 7300-S-13 or in Reference Table 8 on page 7300-S-24).
b) With the unit in Manual Positioning Mode (as indicated by the yellow, MAN light on) and the ADJUST switch
in the “ADJ” middle position, select and enter Command B-4 (or B-5). After command entry, the valve will
be driven to the high (or low) limit position.
c) To change the valve position in +/-1.0 degree steps, momentarily push the INC/DEC switch up or down. If
the INC/DEC switch is held in the up or down position, the valve position setpoint is continuously changed
in +/-1.0 degree steps.
d) After moving the valve to the desired high (or low) limit position, push the ENTER button to save the new
setting. When the ENTER button is pressed, the numbered light(s) and command set ‘b’ light will momentarily turn off, indicating the new value has been stored.
e) To return control back to the 4-20mA position command input, move the MODE switch to the RUN position
(down). The unit is now in RUN mode.

Operating Instructions
Actuator Replacement
The SMARTLINK™ valve actuator assembly is factorycalibrated to ensure 0.1 degree positioning accuracy.
Therefore, the following actuator replacement procedures
should be performed by Maxon personnel or maintenance
personnel trained specifically by Maxon.
Actuator Removal:
1. Disable the process controller connected to
SMARTLINK™ and turn off power. Remove the
actuator access cover using a 4mm Allen wrench and
verify the green power light is OFF.
2. Record the wire color code sequence and then
disconnect the four wires and shield from the terminal
block. Disconnect any conduit fittings.
3. Loosen the clamp collar screws with a 3/16” Allen
wrench.
4. Remove the four M6x1x18 mm screws connecting the
actuator to the adapter with a 5mm Allen wrench.
5. Remove the actuator by holding the actuator housing
and pulling the actuator away from the valve.
Actuator Reinstallation:
1. Inspect the actuator coupling. Identify the type of key
required based on the photos below.
Blind keyway
Open keyway
Blind keyway requires 1/8" x 1/8" square key
Open keyway requires 1/8" x 3/16" rectangular key.
2. Verify the clamp collar is loose and position the screw
head on the left when looking at the clamp collar at the
top.
3. Place the actuator shaft with key into the clamp collar.
Slide the keyed shaft into the coupling key slot, then
rotate the actuator housing so the alignment pin mates
with the pin hole in the valve adapter. The parts are a
clearance fit but should slip together with little force.
Apply pressure until the actuator is flat against the
adapter. Do not apply an excessive force. If the subassemblies do not mate together, recheck that the
clamp is loose and the key is pressed to the bottom of
the key slot.
4. Verify that the valve will close completely. With the
valve closed, the coupling hard-stop pin should be
centered and touching the hard-stop set screw for
butterfly valves. For ball valves, the coupling should hit
on the two vertical hard stop pins in the bracket.
5. With valve in the fully closed position, assemble the
actuator to the valve adapter with four M6x1x18 mm
fasteners using Loctite 242. Use a torque wrench with
a 5mm Allen bit to apply 18in-lbs of torque in an
alternating diagonal tightening sequence.
6. With the valve in the fully closed position, verify that
the clamp collar is seated flush against the coupling
shoulder. Tighten the stainless steel clamp collar with
a torque wrench and 3/16” Allen bit to 170 in-lbs.
7. Make the necessary water-tight electrical conduit
connection. Re-connect the four wires to the terminal
strip per the original color code sequence. Reconnect the shield wire to the terminal strip, keeping it
less than 1” in length.
8. Apply power to the SMARTLINK™ System. Verify the
green power light is ON.
9. Reinstall the access cover and torque the four
fasteners to 18 in-lbs. using a 4mm Allen wrench.
10. Place the Control Interface in manual mode by
executing Command A-0. Then execute Command C2 (Enable Valve Calibration/Check) which places the
actuator in a command mode for calibration. When the
command is entered, if all the lights flash on the
Control Interface, the command was not executed.
When the command is properly executed, the green
diagnostic (DIAG) light in the actuator terminal block
compartment will be on and the unit will no longer
respond to 4-20mA position commands.
11. Execute Command C-1 (Calibrate Valve) which closes
the valve until the hard-stop is found, establishes a
new home (or 0 degree) position, and moves the valve
through all 800 positions. The command takes 2 or 3
minutes to execute during which half of the numbered
lights on the Control Interface flash on and off. When
the command is finished, the Control Interface will
flash all of the numbered lights ON if the command
was not successful. If the calibration failed, repeat the
command a second time.
12. Execute Command C-0 to check the new calibration.
This command takes less than 90 seconds and will
flash half of the numbered lights during execution. At
the end of command execution, if all the number lights
on the Control Interface flash ON and then OFF, the
calibration test failed. Re-mount the valve to the
assembly as described above and repeat the calibration procedure. If the calibration test passed, cycle
power to the actuator and check for a calibration
alarm. (The actuator's green diagnostic light should
now be flashing and the alarm light on the Control
Interface should be off.)
13. Re-enable the process controller commanding
SMARTLINK™.

Checkout Procedure to verify proper relay contact operation
Temporarily disconnect the Data A or B signal to the Valve
Actuator. Within a few seconds, the Alarm relay (connected to
the Control Interface RO1 terminal) should be energized.
After power up, the Control Enable relay (connected to the
Control Interface RO2 terminal) should normally be energized.
Temporarily disconnect the Data A or Data B signal to the Valve
Actuator. Within a few seconds, the Control Enable relay should
not be energized.
Perform Operational Checkout Step #2 or #3 (page 7300-S-6) to
move the valve actuator throughout its full travel range. With the
valve in its maximum position, the High Position Limit relay
(connected to the Control Interface RO3 terminal) should be
energized. With the valve commanded to a position 95% or less
than its maximum position, the relay should not be energized.
Perform Operational Checkout Step #2 or #3 (page 7300-S-6) to
move the valve actuator throughout its full travel range. With the
valve in its minimum position, the Low Position Limit relay
(connected to the Control Interface RO4 terminal) should be
energized. With the valve commanded to a position 5% or more
above its minimum position, the relay should not be energized.
After power up, the Manual Control relay (connected to the
Control Interface RO5 terminal) should not be energized. Put the
SMARTLINK™ in a local manual mode as described on page
7300-S-13. Once the system is put in manual mode, the Manual
Control relay should be energized.
Energize HPC terminal and verify that valve moves to its
maximum characterized position, index #9. (Input function not
supported in Software Version #1.)
Energize LPC terminal and verify that valve moves to its
minimum characterized position, index #0. (Input function not
supported in Software Version #1.)

Desired valve position when a loss of signal (L.O.S.) event occurs. A loss of signal condition
exists if the position command signal drops below 0.05mA. Configuration setting #0, 1, 2, and
3 correspond to the positions defined at index #0, 3, 6, and 9, respectively. Setting #4
corresponds to no position change (i.e. actuator remains in last position before loss of signal).
Desired valve position when adjustment mode switch is placed in the STANDBY position.
(The STANDBY function is not active when the unit is in RUN mode.) Configuration setting #0,
1, 2, and 3 correspond to the positions defined at index #0, 3, 6, and 9, respectively.
Control deadband placed around the position command input signal to eliminate unwanted
actuator movement caused by electrical noise on the 4-20mA position command.
Configuration setting #0, 1, 2, 3, 4, and 5 correspond to a deadband of 0, 0.03, 0.06, 0.13,
0.16, and 0.19%, respectively.
Relay driver Output #3 (RO3) will energize the High Position Limit relay when the valve
position is >= high position limit threshold. This value is automatically set to 1.0 degree less
than the maximum valve position when modified using Commands A-2 or A-5.
Relay driver Output #4 (RO4) will energize the Low Position Limit relay when the valve
position is <= low position limit threshold. This value is automatically set to 1.0 degree above
the minimum valve position when modified using Commands A-2 or A-6.
The automatic ramp function is used during the Valve Position Setup Mode to create a linear
position ramp between the position being adjusted and the two adjacent position indexes.
This provides a position “smoothing” of the valve profile and simplifies valve characterization.
Setting #0 is Auto Ramp OFF and setting #1 is ON.
4-digit electronic passcode to prevent tampering. The passcode is required to modify the
configuration only if the lock is enabled. See Select Lock Enable/Disable configuration below.

Table 8: SMARTLINK™ User Commands - Command Set 'A'
SMARTLINK Commands
Number: Name
Description of command purpose and usage
Command Set 'A'
Command A-0 is used to enter a Manual Positioning Mode that overrides the 4-20 ma, position command
input. To execute Command A-0, the position command signal must first be driven to 4ma or less. If the
numbered lights flash momentarily after entering Command A-0;
a.) the position command may not be less than 4ma,
b.) the adjustment mode switch may be in the STANDBY position, or
c.) unit may be "locked" to prevent tampering.
A-0: Enter Manual
Positioning Mode
After entering Command A-0, the yellow manual light on the Control Interface will be on and RO5 (Relay
Output driver #5) will energize the Manual Control relay (if installed). Once this command has been entered,
the INC/DEC switch can be used to move the valve open or close. If the adjustment mode switch is in the
INDEX position, the INC/DEC switch is used to move between the 19 electronic position "indexes". (See
Commissioning Sheet on page 7300-S-17 for the factor y default positions for each index.)
If the adjustment mode switch is in the ADJ position, pushing the INC/DEC switch up or down changes the
valve position in 1.0 degree steps. If the INC/DEC switch is held in the up or down position, the position is
continuously adjusted until the max/min position is reached. This command should not be executed when
the valve is part of an operating process that requires continuous, closed-loop valve positioning.
A-1: Display Alarm Codes
After entering Command A-1, the INC/DEC switch is used to scroll through all current alarm conditions. If the
red alarm ("ALM") light on the Control Interface is on, one or more alarm condition exists. (See page 7300-S15 for Alarm Codes.)
Command A-2 is used to enter the Valve Position Setup Mode for modifying the 19 position profile. To execute
Command A-2, the position command signal must be 4 ma or greater. (If the numbered lights flash
momentarily after entering A-0, the adjustment mode switch may be in the STANDBY position, or the unit may
be "locked" to prevent tampering.)
A-2: Enter Valve Position
Setup Mode
After entering Command A-2, both the yellow manual light and green run light will be flashing along with 1 or
2 of the numbered lights that are used to indicate the valve's position index. The flashing lights indicate that
one of the 19 position indexes can now be modified using the INC/DEC switch. (For example, if the #1 and #2
light are flashing, position index 1.5 can be adjusted.) The position command signal determines which of the
19 position indexes can be modified. With the adjustment mode switch in the ADJ position, pushing the
INC/DEC switch up or down changes the valve position in +/-0.1 degree steps. If the INC/DEC switch is held
in the up or down position for more than 3 seconds, the valve position is changed in 0.5 degree steps. After
moving the valve to the desired position, the Enter button must be pressed to save the position setting. When
the Enter button is pressed, the blinking position index lights (0-9) and command set light 'a' will momentarily
turn off. See Commissioning Sheet on page 7300-S-16 for a complete description of the valve characterization
procedure.
In the Position Setup mode a maximum movement of 8 degrees from the stored position is permitted. When
the 8 degree limit is reached all of the position index lights will momentarily flash on. If the adjustment mode
switch is in the INDEX position, valve positioning is inhibited and is indicated by a momentar y flash of the
position index lights if an INC/DEC switch adjustment is attempted. Valve positioning is also inhibited if the
position command signal is less than 0.05 ma and is indicated by turning off the position index lights.

Description of command purpose and usage
Command Set 'A'
A-5: Set Max Position &
Min/Max Ramp
Command A-5 is used to enter the Valve Position Setup Mode for adjusting the maximum position (index #9)
and setting a linear position ramp from the minimum to maximum stored positions. To execute Command A-5,
the position command signal, must be 20.00ma, +/-0.15 ma. (If the numbered lights flash momentarily after
command entry, the position command input is not 20ma or the adjustment mode switch is in the STANDBY
position.) After entering the command, both the yellow manual light and green run light will be flashing along
with a flashing #9 light. The valve's maximum position can now be modified using the INC/DEC switch. If the
adjustment mode switch is in the ADJ position, pushing the INC/DEC switch up or down changes the valve
position in +/-0.1 degree steps. If the INC/DEC switch is held in the up or down position for more than 3
seconds, the valve position is changed in 0.5 degree steps. After moving the valve to the desired position, the
Enter button must be pressed to save the position setting. When the Enter button is pressed, the #9 position
index light and the command set light 'a' will momentarily turn off.
In the Position Setup mode a maximum movement of 8 degrees from the stored position is permitted. When
the 8 degree limit is reached all of the position index lights will momentarily flash on. If the adjustment mode
switch is in the INDEX position, valve positioning is inhibited and is indicated by a momentary flash of the
position index lights when an INC/DEC adjustment is attempted. After the command is entered, valve
positioning is also inhibited if the command signal changes from 20.00 ma.
A-6: Set Min Position &
Min/Max Ramp
Command A-6 is used to enter the Valve Position Setup Mode for adjusting the minimum position (index #0)
and setting a linear position ramp from the minimum to maximum positions. To enter Command A-6, the
position command signal must be 4.00ma, +/-0.15 ma. Adjustment of the minimum position is performed
identical to adjustment of the maximum position, Command A-5.
A-7: Unlock Valve
Configuration
Command A-7 permits entry of a 4-digit pass-code to "unlock" the system configuration and position profile for
user modification. A flashing alarm light indicates a "locked" unit. If the alarm light is not flashing, the unit is
already unlocked and the numbered lights will flash momentarily if command entry is attempted. After the
command is entered, the INC/DEC command is used to select a pass-code digit as indicated by the lights.
Once selected, the Enter button should be pushed and the process repeated 3 more times. If the 4-digit
pass-code is correct, the alarm light will stop flashing and be turned off if no other alarms exist. To re-lock the
unit, move the command switch to the RUN position

B-0: Select Loss of Signal
(LOS) Position
B-1: Reserved for future
use
B-2: Select Standby
Position
Command B-0 is a configuration command that permits selection of valve position when a loss of signal event
occurs (below 0.05 ma). After B-0 is entered, the current configuration is shown by one of the numbered
lights. Select an L.O.S. configuration, #0,1,2,3, or 4, using the INC/DEC switch and push the Enter button after
the desired configuration is indicated by the numbered lights.
Configuration #0,1,2, and 3 correspond to the positions defined at index #0, 3, 6, and 9 (max), respectively.
(See Commissioning Sheet on page 7300-S-17 for the default valve position for each index). Configuration #4
corresponds to no position change (actuator remains in last position before loss of signal). The factory default
configuration is #4.
N/A
Command B-2 is a configuration command that permits selection of the STANDBY valve position. After
command entry, the current configuration is shown by one of the numbered lights. Select a standby position
configuration, #0-3, using the INC/DEC switch and push the Enter button after the desired configuration is
indicated by the numbered lights. Configuration #0,1,2, and 3 correspond to the positions defined at index #0,
3, 6, and 9 (max), respectively. (See Commissioning Sheet on page 7300-S-17 for the default position for
each index).
The STANDBY position is useful if an emergency situation occurs during Valve Position Setup and the user
wants the valve to immediately move to a "safe" position, regardless of the 4-20 ma position command. The
valve moves to the STANDBY position when the adjustment mode switch is in the downward "STANDBY"
position.
B-3: Select Deadband
Command B-3 is a configuration command that is used to select the deadband placed around the position
command input signal. If the input signal contains spurious noise, hunting of the actuator may occur. It is
recommended that the source of the noise is eliminated or the 4-20 ma cable type is verified as well as its
shield and ground connections. If the noise cannot be eliminated, the deadband can be increased as a last
resor t.
After Command B-3 is entered, the current configuration is shown by one of the numbered lights. Select a
deadband configuration, #0-5, using the INC/DEC switch and push the Enter button after the desired
configuration is indicated by the numbered lights. Configuration #0,1,2,3,4 and 5 correspond to a deadband of
0, 0.03, 0.06, 0.13, 0.16 and 0.19%, respectively. The factory default configuration is #2, 0.06%.
Command B-4 is a configuration command that is used to adjust the high limit position threshold. Relay driver
Output #3 (RO3) will energize the High Position Limit relay when the valve position is equal to or greater than
the stored high limit position threshold. The factory default is 80.0 degrees and is automatically set to 1.0
degree less than the maximum valve position when modified using Commands A-2 or A-5. If the factory
default or automatic 1.0 degree offset (from a user-selected maximum) is acceptable, this configuration is not
necessary.
B-4: Set Hi Limit Position
Threshold
To execute Command B-4, the valve system must be in the Manual Mode (See Command A-0). With the unit
in Manual Mode and adjustment mode switch in the "ADJ" middle position, push the Enter button and the
valve will be driven to the stored value. Then push the INC/DEC switch up or down to change the valve
position in +/-1.0 degree steps. If the INC/DEC switch is held in the up or down position, the valve position is
continuously changed in +/-1.0 degree steps. After moving the valve to the desired high limit position, the
Enter button must be pressed to save the setting. When the Enter button is pressed, the position index and
command set 'b' lights will momentarily turn off, indicating the new value has been stored.

Description of command purpose and usage
Command Set 'B'
Command B-5 is a configuration command that is used to adjust the low limit position threshold. Relay driver
Output #4 (RO4) will energize the Low Position Limit relay when the valve position is less than or equal to the
stored low limit position threshold. The factory default is 0.00 degrees and is automatically set to 1.0 degree
above the minimum valve position when modified using Commands A-2 or A-6. If the factory default or
automatic 1.0 degree offset (from a user-selected minimum) is acceptable, this configuration is not necessary.
B-5: Set Low Limit Position
To execute Command B-5, the valve system must be in the Manual Mode (See Command A-0). With the unit
Threshold
in Manual Mode and adjustment mode switch in the "ADJ" middle position, push the Enter button and the
valve will be driven to the stored value. Then push the INC/DEC switch up or down to change the valve
position in +/-1.0 degree steps. If the INC/DEC switch is held in the up or down position, the valve position is
continuously changed in +/-1.0 degree steps. After moving the valve to the desired low limit position, the Enter
button must be pressed to save the setting. When the Enter button is pressed, the position index and
command set 'b' lights will momentarily turn off, indicating the new value has been stored.
Command B-6 is a configuration command that is used to set on or off the automatic ramp function. The
factory default is Auto Ramp ON, configuration #1. Configuration #0 is Auto Ramp OFF.
B-6: Set Auto Ramp Adjust
On/Off
After command entry, the current configuration is shown by one of the numbered lights. Select Auto Ramp
ON, #1, or Auto Ramp OFF, #0 using the INC/DEC switch and push the Enter button after the desired
configuration is indicated by the numbered lights.
The automatic ramp function is used during the valve Position Setup Mode to create a linear position ramp
between the position being adjusted and the two adjacent position indexes. This provides a position
"smoothing" of the valve profile and simplifies valve characterization because only 10 of the 19 position
indexes (i.e. index 0, 1, 2, 3, ….instead of 0, 0.5, 1.0, 1.5, etc.) require adjustment. For custom valve
characterization that requires precision adjustment of each of the 19 position indexes, the Auto Ramp function
should be OFF.

tampering. To execute Command C-4, the electronic "lock" must be enabled and the unit must be in the
"unlocked" state. (A locked unit is indicated by a flashing alarm light.) If all the numbered lights momentarily
flash after command entr y, the "lock" function is disabled or the unit is currently locked. See Command C-5 to
enable the lock function or Command A-7 to unlock the unit.
C-4: Enter New Lock
Combination
After the command is entered, the INC/DEC command is used to select a pass-code digit as indicated by the
numbered lights. After the first digit is selected, the Enter button should be pushed and the numbered light and
command set light 'c' momentarily turn off. Repeat the previous digit entr y process 3 more times for a total of 4
digits. After the 4th digit is entered, the number #4 light will turn on and the command set 'c' light will begin to
flash, indicating that a new 4-digit pass-code has been saved and the command is complete.
If the 4-digit pass-code is forgotten, call Maxon for assistance. The factor y default 4-digit pass-code is 0-0-0-0.
Command C-5 is a configuration command that is used to enable or disable the electronic "lock" function. The
factor y default is configuration #0, Lock Disable. Configuration #1 is Lock Enable.
C-5: Select Lock Enable /
Disable
To execute Command C-5, the unit must be in the unlocked state. (The alarm light will be flashing rapidly if the
unit is locked. See Command A-7 to unlock the device.) After command entr y, the current configuration is
shown by one of the numbered lights. Select either configuration #0 or #1 using the INC/DEC switch and push
the Enter button after the desired configuration is indicated by the numbered lights.

Description of command purpose and usage
Command Set 'C'
C-6: Save Profile as
Backup
Command C-6 is a configuration command that is used to save the currently stored valve position profile.
This command is used in conjunction with C-7, Restore Backup Profile, to help ensure that a proven valve
position profile can be restored without re-commissioning if a factory default reset is accidentally performed or
incorrect position adjustments are made during the commissioning process.
To execute Command C-6, the valve system must first be in Position Setup Mode (See Command A-2). With
Command C-6 selected and the unit in Position Setup Mode, push the Enter button. Light #6 and the
command set 'c' light should momentarily turn off, indicating the command has been executed.
C-7: Restore Backup
Profile
Command C-7 is a configuration command that is used to restore a backup valve position profile as the
current operating profile. This command is used in conjunction with C-6, Save Profile as Backup, to help
ensure that a proven valve position profile can be restored without re-commissioning if a factory default reset
is accidentally performed or incorrect position adjustments are made during the commissioning process.
To execute Command C-6, the valve system must first be in Position Setup Mode (See Command A-2). With
the unit in Position Setup Mode and Command C-7 selected, push the Enter button. Light #7 and the
command set 'c' light should momentarily turn off, indicating the command has been executed.
General Command Entry Instructions:
1. A user command can be performed only when the following conditions are all satisfied:
a.) MODE switch is not in the RUN position,
b.) one of the green command set lights (a, b, c) is blinking,
c.) ADJUST switch is not in the STANDBY position, and
d.) unit is “unlocked”. (Condition d. is not required for Command A-7, Unlock Valve Configuration and
Command A-1, Display Alarm Codes.)
e.) For some commands, the unit must be in a specific mode or have the correct 4-20mA command signal
(see command entry requirements listed on page 7300-S-10 or in Reference Tables 8 through 10 on
pages 7300-S-24 through 29).
2. If the a, b, or c command set light is not blinking, momentarily push the MODE switch in the CMD abc position
(up) or, change the position of the rotary CMD SEL switch. This will start the command set light blinking and
permit a command to be entered.
3. Select the desired command set by momentarily pushing the MODE switch upward to the CMD abc position.
Subsequent CMD abc switch entries will change the command set selection as indicated by the green command set (a, b, c) lights.
4. Select the desired command number by changing the position of the rotary CMD SEL switch. When one of the
command set lights is blinking, the command number selected is indicated by the corresponding numbered (09) light being lit.
5. After the command set and number are selected, press the ENTER button. If all of the numbered lights flash
momentarily after the Enter button is pushed, a command entry error has occurred and the command was not
executed. If an entry error occurs, check if the unit is locked (i.e. alarm light blinking) or the ADJUST switch is
in the STANDBY position. If neither condition exists, check the specific entry requirements of the command.
